I have an Eibos 2 spool filament dryer that seems to be reaching it's end of life. Its max dry temp is 70c - I've been able to successfully dry and print PA6-GF and PA6-CF after an extended period of time. It's performance is degraded now and I'm getting banding on my nylons when I print that tell me my filament is not totally dry even though it's been running 24/7. It's time for a new dryer. The good: purpose built filament dryer at $250+ The bad: a similar Eibos dryer they may work after running for several days The ugly: an air fryer that can dehydrate for an 8 hr period at 80c+. I'm leaning towards the Ugly. What do you recommend for air fryers? Other similar cost items that don't require a lot of tinkering? Edit to add photo. Needs better drying, right?

Air fryers don't typically regulate their temperature as closely as a purpose built dryer, and many of them have timers that max out at only a few hours. Not great for overnight drying. If you're doing nylons a lot then you want higher temp capabilities. Sunlu E2 or the West 3D toaster oven conversion. |

I know little about dryers but I have the Sunlu and the 2 things that bother me is there is no gasket around the doors so once it shuts off the humidity starts to build again. Secondly, there is a very low profile slide for opening the door that is VERY hard to pinch to get the door open. It took a 5 star product down to about a 2 or 3 b/c of 2 small if very significant (in my eyes) faults. |

The E2 has a single top cover and is indeed gasketed. Kind of irrelevant though because if the dryer is not turned on then the material should be in a storage container. |

You are correct, but I'm not always there to remove it immediately and when I look the humidity is already moving up. I was under the impression this was made to be printed from given the filament ports, but it also wont seal off to the elements, so it needs to be run while printing, but afterward filament needs to be stored in a drybox. |

Yep. I've got a west3D dryer and am really bad about leaving filament in it

Same thing with the Creality dryers. They're great for drying while printing but crap for storage. |
